2 USB ports and the USB symbol

USB stands for Universal Serial Bus. USB ports are found on computers, both the PC and Mac, and can be used to plug in an external hard drive, flash drive, computer mouse, webcam, keyboard, speakers, and many other items. Today, most USB's are either 2.0 or 3.0, with 3.0 having the fastest read and write speeds.

USB speeds depend on the version being used by the hardware attached to the port and the version of the port itself.
